So it’s the wife’s fault if a husband is unfaithful?
Sounds like the rationale of a true misogynist.
I never said it was her fault, but it does leave him vulnerable to a woman who would love him and is not his wife. About 20% of marriages are functionally sexless. It is quite common for women to sleep with the Alpha males without a ring and then deny sex to beta husband they do marry.
As I said, the proper response to alack of affection is divorce, not infidelity.
